Ancova and lme use
...;t corrected. Covariance analysis seems to represent the best way to do this. But how to perform this by using R ? Actually, we have identify some R functions of interest regarding this matter (lme(), lm() and glm()). For example we plan to do as describe : glm(response~baseline) and then simtest(response_corrected~group, type="Dunnett", ttype="logical") If a mixed model seems to better fit our experiment, we have some problems on using the lme function : lme(response~baseline) returns an error ("Invalid formula for groups"). So : Are fitted values represent the corrected respon...
